Specification of Letters Patent.

Patented Oct. 21,1919.

Application filed May 24. 1917. Serial No. 170.773.

To all whom it may concern: 5

Be it known that I, JOHN E. OSMER, a citizen of the United States, residing at Owosso, in the county of Shiawassee and State of Michigan, have invented certain new and useful Improvements in Cinder and Clinker Pulverizers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its main object to provide more particularly a novel means for disposing of cinders and clinkers which are discharged from the fire boxes of locomotive furnaces, thus rendering the use of cinder pits unnecessary at round houses and the like.

In attaining the above end, the cinders, clinkers and other material discharged from the fire box are pulverized and deposited in an ash pit or pan, a further object being to provide simple and eilicient means for discharging the material from said pan whenever required, either simultaneously with depositing of such material in the pan, or after a quantity thereof has accumulated. V V H V V V 7 With the foregoing general objects in view, the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which form a part of this specification and in which:

Figure 1 is a side elevation of a portion of a locomotive showing the invention applied and illustrating primarily the driving means for the pulverizing rollers;

Fig. 2 is a longitudinal section through the invention and associated parts;

Fig. 3 is a horizontal section on the plane of the line 33 of Fig. 2; and,

Fig. 4 is a vertical transverse section on the plane indicated by the line 44t of Fig. 2.

In the drawings above briefly described, the numeral 1 designates a fire box of a lo comotive, 2 the grate of said fire box and 3 has reference to the usual or any preferred type of ash pit or pan below the grate 2.

Extending either transversely or longitudinally across the pan 3, are horizontal ribbed crushing rollers l, the ribs 5 of said rollers either extending in truly longitudinal directions in respect to said rollers, or spirally around the same. The ribs will in most cases intermesh as depicted in Fig. 2 but in some cases, the rollers might be spaced apart a slight distance. 1

Alternate rollers 4 are shown equipped on one end with worm gears G meshing with worms 7 on a drive shaft 8, said shaft be ing rotated by any preferred means such as the small steam engine indicated at 9. The

' worms and worm gears are preferably used for driving the crushing rollers, but it will be obvious that any suitable means could well be employed. If the ribs of the rollers intermesh, it will be suflicient to drive only the alternate rollers as shown, but if said rollers are spaced apart, driving means will preferably be employed for all of the same.

Spaced above the downwardly traveling and converging faces of the adjacent rollers, are fixed crushing bars 10 provided with ribs 11 or otherwise roughened on their lower faces to coact with the ribs 5 in pulverizing the clinkers and the like before discharging the latter into the pan 3.

As usual, the bottom of pan 3 is in the form of one or more hoppers 12, according to the sizeof the locomotive,the sides of.

said hoppers being shown equipped with sliding doors 13 which may be opened and closed at will by any preferred means such as the operating rods 14: illustrated in the drawings. When the doors 13 are opened, blasts of steam or other fluid pressure are forced outwardly therethrough by means of suitable nozzles 15, whereby the pulverized material will be blown from the pan and deposited along the track.

In some cases, although the invention is preferably located below the locomotive grate, it may well be employed in place of said grate, the action being the same. Furthermore, although the invention is best adapted for use on locomotives, its application is not limited to any particular field and it is also to be noted thateven though certain specific details ofconstruction have been shown anddescribed for illustrative purposes, numerous minor changes might well be made within the spirit of the invention as claimed.

I claim 1. The combination with a railway vehicle having a firebox provided with a shaking grate, of means carried by said vehicle for receiving and crushing the cinders and clinkers discharged through said grate and for depositing them along the railway.

2. The combination with a railway vehicle having a firebox provided With-a shaking grate, of means carried by said vehicle for receiving and crushing the cinders and clinker-s discharged through said grate, and means for discharging the crushed material along the sides of the railway.

3'. The combinationwith a firebox having a shaking grate and an ash pit under said grate, of a cinder and clinker crusher extending entirely across said ash pit in both longitudinal and transverse directions and of substantially the same area as said grate, for crushing the cinders and clinkers discharged through the latter.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
